Trial details

Researcher(s) John Sykes (John Sykes Rural Consulting)
Year(s) 2010
Contributor Riverine Plains
Trial location(s) Balldale, NSW
Wheat inputs experiment locations
Aims

To assess if the previous year's results from this experiment could be replicated in a year with average to above average growing season rainfall (GSR).

Key messages
  • In high rainfall years, 70 plants /m2 will produce lower yields than crops with higher plant numbers, unless some nitrogen is applied at the five-leaf stage (GS 15).
  • If nitrogen is applied at GS 15, similar yields can be obtained.
  • There may be opportunities to use phosphours in crop to maximise yields.
  • More work needs to be carried out to confirm this.
  • Lower than optimal tiller numbers can still produce acceptable yields and water use efficiencies (WUE) in wet years.
